Technical solution: a kind of rotatable unilateral micro-hole aerator of the utility model, including air duct, the snorkel
Road is threadedly coupled by screw thread with air inlet pipe, and the air inlet pipe is communicated far from one end of air duct with gas chamber, and the gas chamber is logical
It crosses rotary components to be fixedly connected with air inlet pipe, gas chamber is uniformly distributed on peripheries with gas chamber trunnion axis same level and communicates with gas chamber
Several aeration tubes.
Further, the rotary components include rubber mount and swivel bearing, and the swivel bearing lower end is provided with down
Pressure pad, is provided with middle pressure pad between swivel bearing and rubber mount, the rubber mount upper end is provided with pressure pad；Middle pressure pad with
Lower pressure pad can fix swivel bearing, and upper pressure pad and middle pressure pad can fix rubber mount, and rubber mount is in chamber inflated by air pressure
Gas chamber inner wall can be close to by influencing its surrounding, reduced gas leaking from swivel bearing, enhanced the air-tightness of gas chamber.
Further, the air inlet pipe is provided with filter screen close to one end of air duct, crosses air filtering sundries.
Further, the aeration tube side is provided with two rows of aerating pores, and the aerating pore is tapered, aerating pore
On be covered with arc filter screen with the ipsilateral setting of aerating pore, aerating pore can be prevented to be blocked.
Further, the plenum roof is provided with dismountable gas chamber top cover, and it is convex that gas chamber outer wall top is provided with arc
Play lines；Gas chamber top cover is connected through a screw thread, convenient for the installation and maintenance of aerator；Arc convex lines increases resistance, benefit
Water body agitation is driven when gas chamber rotation.
The utility model has the advantages that the utility model can avoid aeration tank or the sludge being aerated at bottom portion dead angle by unilateral aeration
Deposition, and reinforced bottom sewage is oxygenated, and evades aeration blockage drawback；It is filled in addition, air blast computer room is sent into air through air filtration
A possibility that setting, then through filter screen at air inlet pipe, impurity in air can be removed and brought into, reducing aeration blockage；Gas is through gas chamber
Enter sewage into aeration tube, then through aeration tube side aerating pore, because aerating pore outgassing direction is consistent, can produce promotion
Power can drive gas chamber to rotate, to stir water body, be sufficiently mixed gas-liquid, improve oxygenation benefit without additional energy source input,
And then improve the ability of microbiological oxidation decomposing organic matter.
